IVILLIAM W. EWING, OF BUTLER, PENNSYLVANIA.

DOOR-SECURER.

SPECIFICATION forming part of Letters Patent No. 473,305, dated April19, 1892.

Application filed January 4, 1892.

T00 whom it may concern.-

Be it known that I, WILLIAM WV. EWING, a citizen of the United States,residing at Butler, in the county of Butler and State of Pennsylvania,have invented certain new and useful Improvements in Door-Securers, asset forth in the accompanying; drawings, forming part of thisspecification, in which Figure 1 is a perspective view of my doorsecurerin position. Fig. 2 is a side view of the same detached.

My invention relates to means for securing doors and analogousstructures against being opened byintruders and those not entitled toaccess to the premises; and my invention consists of the constructionand combination of devices forming the improved securer, which I shallhereinafter fully describe and claim.

To enable others skilled in the art to which m yinvention appertains tomake and use the same, I will now describe its construction and indicatethe manner in which the same is carried out.

In the said drawings, A represents a door, window, or analogous device,and B is the jamb orframe of the same, both of which may be of the usualor of any well-known construction. To this door the securer is fastened,so that when the door is closed and the securer in position itwill bepractically impossible to open the door from the outside. This securerconsists, essentially, of a plate 0, having one end 0 bent and adaptedto be driven into the inside of the jamb or frame B, so that when thedoor is closed it abuts against the plate to hold it againstdisplacement. If desired, the bending of the plate may be dispensed withand the plate held by screws or nails Without departing from the spiritof my invention. This plate projects from the plane of the face of thedoor and extends into the room or apartment farenough to furnish abearing for the cams or eccentric heads E of the levers D, which aresecured to said plate by a bolt F, passing eccentrically through thehead or cam and plate and secured by a nut cl. The cams Serial No.416,955. (No model.)

door is resisted by the cam on the inside of the same and furtherresisted by the opposite cam bearing against the door-jamb. From thecams or eccentric heads extend the leverarms D,by which they areoperated, and these levers carry at their lower ends suitable bells G,which are caused to vibrate and ring an alarm when the door is moved,and thereby warn theinmates of the house of the presence of intruders onthe outside. Through the cams or eccentric heads holes e are made toreceive a pin f, by which the two cams are held together, and said pinby engaging the edge of the plate 0 prevents the cams being turned fromthe outside and also enables the levers to be adjusted to difierentpositions and the device to be applied to doors of differentthicknesses.

To release the door, the cams are thrown back until their short sidesare presented next to the door, when a sufficient space is left topermit the door to open.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a door-securer, a plate fitted between the door and its casing orframe and projecting inwardly, in combination with two cams oreccentrics fulcrumed to the inner end of said plate, one upon each side,and having projecting arms or levers by which they are moved,substantially as herein described.

2. In a door-securer, a plate adapted to be secured between the door andits frame or casing and projecting inwardly, the cams or eccentric headsfulcrumed to the inner end of said plate, one upon each side, andadapted to bear on the door and door-frame, respectively,and levers orarms projecting from the cams and provided with bells,which sound analarm when the cams are moved, substantially asherein described.

3. In a door-securer, the supporting-plate with its cams or eccentricsadapted to bear one upon the door and the other upon the frame thereof,said cams having holes adapted to receive a pin for locking andadjusting them, substantially as herein described.
